Its strange how the names get used over and over. I know an Oliver and Nora Hillhouse. Oliver died just a few years ago, but Nora is still alive.
I know this doesnt help you much since you were looking for information on the Oliver and Nora buried in Noxapater.
The reason I wrote you is because my dad, Johnny R. Hillhouse was born in Noxapater. He died in 1976 in an electrical accident in Nebraska. His mom was Jewel Hillhouse. His dad (my grandfather) is Robert Hillhouse. Jewel died of cancer in 1968 or so. Robert is now remarried to a Nora.
